Objective:To explore the relationship between foot yangming meridian and stomach.Methods:Changes of principal total power of gastric electrogram and gastric impoedamce after acupunctiering points of foot yangming meridian were detected by wsing amalytical imstrument of electrogastrogram freguence spectrum and gastric impedance freguence spectrum in 50 healthy volunteers.Results:Principal total power of gastric electrogram were increaseal significantly after acupuncturing sibai point.Principal total power of gastric impedanre were increased obviously after acupuncturing Zusan Li and sibai point...
